English: Diagram of three binary dwarf planet systems, showing approximate true colors, separation distances, and diameters to scale. Each system's barycenter locations are marked with red crosshairs. The following dwarf planet systems are shown from top to bottom: Pluto, Eris, and Orcus. The scale of the original-resolution image is 10 km per pixel.

• The diameters of Pluto and Charon are taken from Nimmo et al. (2017). The separation distance of Pluto-Charon is taken from Brozovic et al. (2015). The Pluto-Charon barycenter position is calculated from Stern et al. (2015)'s masses for Pluto and Charon.
• The diameter of Eris is taken from Sicardy et al. (2011) while Dysnomia's diameter is taken from Brown & Butler (2023). The separation distance of Eris-Dysnomia is taken from Holler et al. (2021). The Eris-Dysnomia barycenter position is calculated from Holler et al. (2021)'s system mass and Brown & Butler (2023)'s Dysnomia mass.
• The diameter of Orcus is taken from Brown & Butler (2018) while Vanth's diameter is taken from Sickafoose et al. (2019). The separation distance of Orcus-Vanth is taken from Grundy et al. (2019). The Orcus-Vanth barycenter position is calculated from Grundy et al. (2019)'s system mass and Brown & Butler (2023)'s Vanth mass.
